代码如果正确，会直接执行清理命令，如果代码引发错误，会在except子句进行处理，最后才会采取清理命令。

# Python code to illustrate

# clean up actions

def divide(x, y):

try:

# Floor Division : Gives only Fractional Part as Answer

result = x // y

except ZeroDivisionError:

print("Sorry ! You are dividing by zero ")

else:

print("Yeah ! Your answer is :", result)

finally:

print("I'm finally clause, always raised !! ")

# Look at parameters and note the working of Program

divide(3, "3")

Output :

I'm finally clause, always raised !! 

Error:

Traceback (most recent call last):
